Hi, I'm posting this series again after ~3 years that introduces UDF file system support in UEFI. Why? Because Laszlo (or Red Hat) seemed to be interested in such support.
I started working on this driver just as an excuse to learn UEFI development at that time. This work isn't based on any previous one and it's BSD licensed. I also *never* intended to replace it with the default FAT file system. On the contrary, I was looking to give people an opportunity to use file system features that current FAT file system lacks. This series was never reviewed or fully tested. I basically used Linux and mkudffs[1] to test different UDF disks, as well as booting a Linux (EFI stub) rootfs from UDF file systems. Please, I'd really appreciate if some of one could help reviewing or testing it. Note that UDF file system support was *only* added to OVMF platform and it's disabled by default through UDF_ENABLE build option. There's also a feature PCD flag that turns on or off parsing of UDF volumes during partition discovery in PartitionDxe driver.
